Abstract：
In order to study the seismic behavior of the 3D scale frame, this paper designed 1 PEC column steel beam end plate connection the 3D scale frame scale test samples under cyclic loading. Analysis of test data, ultimate bearing capacity is 453.2 kN, average ductility coefficient is 3.2, the displacement angle between the layers is less than the norm limit, energy dissipation factor is between 2.11~2.90, the PEC column type steel beam end plate connection space frame has excellent seismic performance.
